Many thanks
Anomoia purmunda
On a google this looks remarkably similar to the species you suggets Further to bthis you may note that it is found on
Crataegus laevigata - Midland Hawthorn (Rosaceae) on which the larva is known to feed I noted the fly doing a strange little dance holding its wings at right angles to the body is it about to oviposit ????
Thank you

Indeed Anomoia purmunda (I found it, the Hawthorn triggered me

).
The display you witnessed is not ovipositing, in that case it examines the fruits with it's tongue!
The display you mention is used in mating rituals, mainly males towards females, but Tephritids are also known to display this behaviour in order to scare of potential predators. So perhaps it saw you as the threat

But I have also seen it while no predators or potential mates were present..
